-sTUD AND BUTTON FASTENING.

p `Specification of Letters Patent No. 12,725, dated April 17, 1855.

To all whom t may concern.'

Be it known that I, SAMI.. HOPKINS,

" of Providence, in the county of Providence f and State-,of RhodeIsland, have invented a "new and Improved Fastening for Shirt- Studs, Buttons, `6to.; "and yI do hereby declare that the following is a full, clear,l and exact description of the same, `reference being had to the annexed drawings, Inaking a part of this specification, in which*-w Figure 1, is a back view of my improved fastening applied to a shirt stud. Fig. 2, is

a longitudinal section of the tube'of the stud, "showing the y spiralspring within it. Fig. 3,

is a side View` of the fastening.v

Similar letters of reference indicate corresponding parts intheseveral figures.

f The nature of the invention consists in the peculiar construction of the fastening, which will bejfully shown anddescribed hereafter. To enable others skilled in the art tofully f understand and construct my invention, I

will proceedto describe it.

A, representsthe front disk or plate of the stud, and B, `is a tube attached to the back part of the disk or plate A, at about its l center and projecting from it at right angles `as shown, in Figs. 2 and 3, saidtube 4forming the lshankof the stud.

At theouter end ofthe tube B, ithereis `pin (a) which passes transversely` across the i end of the tube, and wit-hin` the tube there is tted a spiral spring .(b) j as shown in Fig. 2.

i "The outerendof the tube "B,is slotted attwo oppositeipoints `and asmall bar (.0)

insertedin the slots, `designated (d) Figs. l and Q,and between the spring (b) and the i pin `(a),|the pin fitting in a recess (e) in the" outer edge of the bar andat its center, as clearly `shown in Figswl `and 2. 'The bar (o) has knobs one atA each end, which `knobs prevent the bar from passingout ot fthe slots (d).

The spiral spring (b) keeps the recess in the bar (c) over the pin (a) as shown in Fig. 2.

The stud is adjusted in the proper eyelet holes in the garment by depressing or Ashovingv the bar (c) toward the disk or plate A,

garment and the bar (e) on the inner side,

the tube B, being in the eyelet holes, see Fig. 3,` (a) representing the eyelet holes of a garment.

The above invention is sirnple,'and effectually secures the stud or button to the garinent and there `is no dangerof the bar (c) being casually displaced so as to allow it to pass out of the eyelets.

Having thus described rny invention, what I claim as new and desire to secure by Letters Patent, is,

The construction of theY fastening as herel in. shown and described, viz, having the `shank of the stud orlbutton, formed of a `tube B, whichcontains a spiral spring (b) and having a bar (c) fitted in slots (cl) in the outer end of said tube and between the outerend of the spiral spring (ZJ) and a pin (a) attached tothe outer end of the tube. The outer side of the bar (c) being pro videdwith a recess (e) which, by Ineans of the spring is kept over the pin (a.) and the bar (c) consequently secured in a trans-` verse position with the tube B.
